a) for high-end cleanroom applications (PUC 44 – 3)
b) for standard cleanroom applications (PUC 44 – 2)
c) for control cabinet installation (PUC 44 – 1)
Values, curves, bar graph, vector can be displayed
Display of up to four values (any phys. / chem. values) in one display, free designation of the channels
Differential pressure transmitter can be connected external
4 individual alarms LowLow/Low/High/HighHigh for any input can be defined. Signalling takes place as a text and optionally with colour change. The individual alarms are retained while the triggering criterion for the alarm is pending.
A collective alarm (of previously defined individual alarms) triggers the acoustic signal. The acoustic alarm is switched off by touching the screen.
The user only has the right to change the released views and to switch off the collective alarm. The user needs no password for this.
The configuration takes place in multiple languages, menu-controlled and via touch operation (without parameterisation software). It can be performed in the factory or by the commissioner.
A one-level password system with at least 6 digits according to GAMP 5 permits access to the configuration by the commissioner or the process officer.
Recording of data is not intended (no logging function). This facilitates validation.
The respective current values of the inputs and the condition of the alarms are available via Modbus RTU at all times and BACnet MS/TP
